Abstract
A system for detecting wear in a flush valve includes at least one pressure sensor adapted to measure a water pressure within the flush valve and at least one microprocessor in communication with the at least one pressure sensor. The at least one microprocessor is configured to determine the water pressure within the flush valve measured by the at least one pressure sensor at or after a predetermined time following operation of the flush valve that is equal to or exceeding a known time required to reseal the flush valve during normal operation, compare the determined water pressure with a pressure value sufficient to reseal the flush valve during normal operation, and determine if the flush valve is worn based at least partially on the comparison. A method and apparatus is also disclosed.
